Hi, I just bought big pack DVD+R 8x Memorex (CMC MAG E01) and tested those with good old 107v2b5d firmware. The results were quite OK.
Then i tried some other firmwares Maddog 2f8 and NEW 2500v3-2 and 2510v3-2, because i thought burning results will get better, but not. The results were horrible, i had to back 107v2b5d.
